NPC.xml :

<?xml version="1.0" encoding="UTF-8"?>
<npc name="Senzu Seller" script="data/npc/scripts/potion seller.lua" walkinterval="2000" floorchange="0">
<health now="150" max="150"/>
<look type="154"/>
<parameters>
<parameter key="message_greet" value="Hello |PLAYERNAME|. If need any heal item's, ask me for a trade."/>
      <parameter key="message_farewell" value="Good bye."/>
<parameter key="message_walkaway" value="Farewell then.." />
<parameter key="module_shop" value="1" />
<parameter key="shop_buyable" value="" />
</parameters>
</npc>

Poion seller.lua :

local keywordHandler = KeywordHandler:new()
local npcHandler = NpcHandler:new(keywordHandler)
NpcSystem.parseParameters(npcHandler)
local talkState = {}

function onCreatureAppear(cid)                npcHandler:onCreatureAppear(cid)            end
function onCreatureDisappear(cid)            npcHandler:onCreatureDisappear(cid)            end
function onCreatureSay(cid, type, msg)            npcHandler:onCreatureSay(cid, type, msg)        end
function onThink()                    npcHandler:onThink()                    end

local shopModule = ShopModule:new()
npcHandler:addModule(shopModule)

shopModule:addBuyableItem({'senzu'}, 2673, 10000, 'senzu')

npcHandler:addModule(FocusModule:new())

Try removing those lines:
<parameter key="module_shop" value="1" /> <parameter key="shop_buyable" value="" />
